More particularly, the present invention relates to the transmission of video signals from satellite antenna electronics through glass windows to, for example, residential buildings or other structures of office buildings, and the transmission of power from the interior of the building to the antenna via glass electronic. Fanzhi Technology includes several systems for transmitting single-band or narrow-band RF signals from mobile phone antennas through car glass windows. Part of the mobile phone system uses ........................ to be formed in Yan Yan. Zu Zhe grid. The Jt capacitor board uses the antenna to output power receiver. — —.............- —............ ________ Other mobile phone systems use the first slot antenna to radiate telephone signals through the glass And a second slot antenna to receive the signal and guide the signal to the receiver. Mobile phone systems are designed to operate on special carrier frequencies. The satellite video system provides video signals from antennas associated with the antenna to a typical receiver located in a home, office building, or car. The video signal is carried by a 7 5 Ω coaxial cable. The power supply for Shuxing Electronics is provided by the receiver on the same axis cable. The installation of this type of satellite TV system requires the antenna signal outside the building to transmit the RF signal to the receiver inside the building and the receiver to transmit the cyanogen source to the antenna electronics. Typical installations require perforations in the walls or high frames for coaxial electrical passage. In many cases, the construction of holes in the wall is unpleasant, and many people do not want their walls to be holed. In renting a house or some commercial property, it is not allowed to make holes in the wall. And the hole in the body of the car is even more unacceptable to the owner of the vehicle. The mobile phone system, because it is single frequency or narrow frequency, cannot be used according to the size of the paper.

Description of the invention (5) The power supply system is a satellite known as "a power supply that can be switched between 12VDC or 18 VDC depending on the needs of the system. The signal from the satellite is divided into vertical and horizontal polarization. The voltage supplied to the satellite electronics is determined by the vertical or horizontal polarized signal received by the receiver. The power supply in accordance with the present invention meets the power requirements of conventional satellite television systems. Referring to FIG. 2, the indoor interface part includes a conductivity connected to the coaxial cable 8 14. The coaxial cable 8 is used to receive the DC power from the receiver 9 of FIG. The DC power supply from the receiver 9 supplies power to the interface cyano circuit and outdoor satellite electronics 11, as shown in circle 1. The power supply then flows from the coaxial cable 8 through the guide 14 to the inductor 16. Inductor 16 prevents the RF signal from entering the power transmission circuit after the component. Inductor 16 is connected to conductor 18 at contact 20. The indoor interface circuit portion 10 is preferably formed on a printed circuit board (not shown). It is better to form an inductance with a small inductance of the same length as the hip guide on the circuit board. The inductance 16 preferably has an inductance value of about 2 OnH, and can be accomplished by forming a parallel portion of the conductor on the black printed circuit board. In Figures 2 and 3, the printed circuit is shown as inductance 16. Siji conductor inductance is displayed in a conventional manner. The voltage regulator 22 is connected between the contact 20 and the +5 VDC source.容容 2 6 is connected between the input of the voltage regulator 2 2 and ground to prevent AC noise from entering the regulator 22. The capacitor 26 preferably has a capacitance value of about 0.1 F. Voltage regulator 2 2 is connected to capacitor 24 and bypasses any AC noise in the output of voltage regulator 2 2 to ground.

Description of the invention (6) The susceptible wave network including capacitors 2 8-3 0 and inductance 3 1 can prevent switching transients from coupling back to the coaxial electric nipple 8. "Capacities 28 and 30 preferably have a capacitance of about 3.3 " F, and fashion capacitor 29 preferably has a capacitance value of about 0.3 " F. The filtered DC power is then conducted to the tapping inductor 3 2 and has a movable core 3 3. The inductance 32 is located near the glass window 34. The end of the M sense 32 is connected to the capacitor 36, so the inductor 32 and the capacitor 36 are connected in parallel. The capacitor 36 preferably has a capacitance value of about 100 PF. The parallel combination of the inductor 3 2 and the capacitor 3 6 is connected to the MOSFET device 3 8, which converts the DC power input to the inductor 3 2 into an alternating magnetic field, and then uses magnetic induction to transmit the power through the glass 3 4 the gap formed by the thickness. As shown in Fig. 3, the external part of the interface circuit including the inductor 40 is installed near the glass window 34. It must be noted that the glass window 34 remains intact without any holes or grooves. The time-varying magnetic field generated by the inductance 3 2 is axially separated by the coil forming the inductance 3 2. Particularly well, the magnetic coil generated by the inductor 3 2 extends to the area occupied by the inductor 40. The time-varying magnetic field generated by the inductance 32 induces a current in the sense 40. The power supply circuit transmits the m source through the dielectric gap to the transmission line 10, and the power transmission line 10 is connected to the electrons used for the antenna. Due to the dielectric gap, there is no continuous core to link the magnetic flux generated in the primary inductor 32 to the inductor 40. Due to the inherent limitations of the star system on the available power supply, the coupling efficiency must be at least 60%. Subsequently, it is explained how the power supply transmission circuit achieves this efficiency through this glass gap.

Description of the invention (8) The output of the voltage regulator 70 also provides a bias voltage to the amplifier 98, which is included in the RF signal transmission circuit. With reference to gardens 1 and 3, it is best to provide a coaxial cable 10 for the fashion connection between antenna antenna 1 1 and the interface circuit, as is commonly used in this application. The inductance 2 0 2 with an inductance value of approximately 2 Ο nH is connected to the coaxial circuit 10 and the voltage regulator 70 to provide a conduction path for DC power, which is transmitted to the antenna via the transmission line. 6 Achieving the required source transmission efficiency through the glass 34 generally requires the hurricane signal to operate at the vibration frequency indicated by the inductor 40 and the capacitor 42. The resonance frequency is the maximum power transmission frequency. The system is preferably constructed to operate at a resonant frequency of about 60 KHz. However, for example, the thickness of the glass, temperature vibration, component aging, and other environmental factors can cause the resonance frequency to deviate from 60 KHz. In order to keep the frequency in the inductors 32 and 40 at the resonant frequency, the present invention includes a feedback network to control the DC source to convert the input to the inductor 32 and the frequency of the magnetic induction transmission through the interval. Referring again to FIG. 3, the feedback network includes the capacitor plate 100 connected at the contact 1 0 3 to the capacitor 4 2 and the capacitor plate 102 connected to the inductor 40 at the contact 10 4. The board 1 0 5 is installed close to the glass 3 4 relative to the board 1 0 0, and the similar board 1 0 7 is installed close to the glass 3 4 relative to the board 1 0 2. The board pairs 1 0 0, 1 0 5 and 1 0 2, 1 0 7 are used to provide capacitive coupling through the dielectric glass 34. Capacitive coupling using two sets of boards provides balanced differential dynamics through terminals G1 0 1 and G1 0 2 to avoid sending back spurious common mode noise to the "back to the network." The signals on terminals G 1 0 1 and G 1 0 2 are input to the paper wave scale as shown in Figure 2 and the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applicable 11--------- -^ ------ 1T ------ Φ 0 (please read the precautions on the back before filling in this page) A7 B7_Printed by the Ministry of Economic Affairs, Central Bureau of Samples and Printing, Beigong Consumer Cooperatives 9) The amplifier 1 1 〇. The amplifier 1 1 0 has a bias voltage source Vb connected to the resistors 1 0 8 and 1 0 9, which are connected to the amplifier inputs G 1 0 1, and G 1 0 2 respectively. The signal input on terminal G 1 0 2 is related to G 1 0 1 reversal. 》 The return circuit also includes a voltage divider (not shown) to measure the performance of the return signal into a combination for input to the amplifier 1 10 〇 振 ®. When the power conversion circuit is operating, the voltages on G 1 0 1 and G 1 0 2 are equal in magnitude and 180 ° out of phase. If the frequency deviates from the spectral vibration frequency, a phase difference will occur between the movement of the inductance 32 and the time between G 1 0 1 and G 1 0 2. The amplifier 110 is preferably a linear amplifier with a differential input. Therefore, only the signals fed back by the capacitors 100 and 102 without being amplified are amplified. The differential input that reaches the linear amplifier and leads to the enhancement of the in-phase signal at the resonance frequency forms a circuit that oscillates at the resonance frequency of the power transmission circuit. Even when the resonance frequency deviates from the main 60 KHz value, the oscillator will track the inter-resonance resonance frequency. The phase response of the suspected feedback signal fed back to the amplifier on the differential input ensures that oscillations only occur at the actual response frequency, even if they change with temperature and other environmental parameters. The amplifier 110 must be very fast so that the amplified signal is free from phase errors at the resonant frequency. The time delay between the input and output of the amplifier 110 is preferably 200 n s or less. The maximum phase error obtained is less than 5 °. The output of the amplifier 1 1 0 is input to the resistance 1 1 2, which is preferably about 2KΩ. The signal input to the resistor 112 is a rectangular wave, which is the analogy of the signal output from the Sense 40 and Cyan capacity 4 2 to the negative signal connected to it.

The output of one MO S F ET is grounded, while the other MOSFET is closed. DC power is applied to the center tap of the inductor 32, and its opposite ends alternate between the ground level and approximately twice the voltage supplied to the center tap of the helper 32.
